Ewing — New Acarina from India. 117 



broader than the tarsus and two-thirds as broad as long. Posterior 

 pair of legs slightly longer than the second and third pairs. The 

 femora of the last two pairs of legs are each provided with a triangular 

 tooth on their posterior margins near the base. The tarsi of the three 

 posterior pairs of legs are all very long and tapering. 

 Length, 0.40 mm.; breadth, 0.38 mm. 



In moss. From Nilgiri Hills, South India. Described 

 from one male and two females. 



Uropoda postgenitalis n. sp. 



PI. XXX V. /. 3. 



Color reddish brown; margins of the body darker than the rest of 

 the body. Integument thick and with shallow pits; pits, though rather 

 evenly distributed, are somewhat irregular in shape and size. 



Mouth-parts rather small and hidden by a slightly projecting an- 

 terior, roundly curved, margin of body. 



Body almost as broad as long, subcircular in outline with margins 

 slightly roughened. Body clothed above with hairs that are unique 

 in their structure. They each possess a single stalk-like base, but this 

 basal stalk is soon resolved into three or even four elements. Of these 

 different elements one is always much larger than the rest, and may 

 be considered as composing the main body of the bristle. The other 

 smaller elements which arise not far from the base of the bristle, 

 extend along the larger one like whip-lashes. These bristles are ar- 

 ranged as follows: there are two rows of seven bristles each which run 

 longitudinally, one on each side of the median line; a row of marginal 

 bristles which completely encircles the body, of these there are about 

 thirty; about an equal number scattered over the upper surface of the 

 abdomen in no special order or arrangement. 



Genital opening of the male large, circular and situated behind the 

 last pair of coxae! Epigynium of female very long, fully twice as 

 long as broad, extending from the front margin of the second coxae to 

 the hind margins of the fourth coxae. It is widest near its middle 

 and is narrowly rounded in front and truncate behind. 



Excavations for the legs moderate, but snugly containing them when 

 folded. Last three pairs of legs subequal. The femora are the stoutest 

 segments while the tarsi are long and tapering. 



Length, 0.52 mm.; breadth, 0.42 mm.
